Error when using hooks in PrimaryNavbar

[Webibi]

Hi,

I am trying to modify the Client Area primary Navbar for visitors only. I have created a .php file in the includes/hooks directory.

          <?php
          use WHMCS\View\Menu\Item as MenuItem;
          add_hook('ClientAreaPrimaryNavbar', 1, function (MenuItem $primaryNavbar)
          {

          $primaryNavbar->getChild('Announcements')

          ->setLabel('Domain Name');

          $primaryNavbar->getChild('Announcements')

          ->setUri('https://.../domain');

...

 

I used hooks and it seems to worked as intended without any issues... But as soon as a client logs in, the site bugs. See the attached error message.

Is it possible to modify the Primary Navbar display for visitor while the client area Navbar remains unchanged for logged client?
